FunctionReceptor for hyaluronic acid (HA). Mediates cell-cell and cell-matrix interactions through its affinity for HA, and possibly also through its affinity for other ligands such as osteopontin, collagens, and matrix metalloproteinases (MMPs). Adhesion with HA plays an important role in cell migration, tumor growth and progression. Also involved in lymphocyte activation, recirculation and homing, and in hematopoiesis. Altered expression or dysfunction causes numerous pathogenic phenotypes. Great protein heterogeneity due to numerous alternative splicing and post-translational modification events.
Tissue specificityIsoform 10 (epithelial isoform) is expressed by cells of epithelium and highly expressed by carcinomas. Expression is repressed in neuroblastoma cells.
Sequence similaritiesContains 1 Link domain.
DomainThe lectin-like LINK domain is responsible for hyaluronan binding.
modificationsProteolytically cleaved in the extracellular matrix by specific proteinases (possibly MMPs) in several cell lines and tumors.
O-glycosylated; contains more-or-less-sulfated chondroitin sulfate glycans, whose number may affect the accessibility of specific proteinases to their cleavage site(s).
Phosphorylated; activation of PKC results in the dephosphorylation of Ser-706 (constitutive phosphorylation site), and the phosphorylation of Ser-672.

Immunohistochemical analysis of Human prostate cancer cell xenograft tissue, staining CD44 (red) with ab24504.
Tissue was fixed with paraformaldehyde, permeabilized with 0.4% Triton X-100 and blocked with 10% serum. Samples were incubated overnight with primary antibody (1/100) overnight at 4°C. An AlexaFluor®555-conjugated anti-rabbit IgG (1/1000) was used as the secondary antibody.
